There is also a OSciM TileStache Provider about vector-tile-server

oh, there is also a start of documentation for the protocol, trying to imitate the tounge of a RFC..

Thanks for pointing me in the right direction! . I only saw
https://github.com/artemp/VectorTileMap/blob/pre-lib/VectorTileMap/TileData.proto which didn't match oscim or pbf MapDatabase.java. I guess I've learnt how protobuf works internally now :).

So https://github.com/jeffdameth/TileStache/blob/master/TileStache/OSciMap/TileData.proto is 0.2 protocol ? Or am I missing something.

Not having a fixed list of key=val would be great. Have you thought about transmitting styling information to the client rather then OSM tags ?

Also, what are your thoughts about using proto-buf based protocol for browser based rendering ?

Thanks for the great app!

At least when using pbf with Android a custom parser is definitely of
advantage, having looked at the code that the generator spits out...

So
https://github.com/jeffdameth/TileStache/blob/master/TileStache/OSciMap/TileData.protois 0.2 protocol ? Or am I missing something.

yes, it's the current version read by oscim.MapDatabase and used when
choosing OpenScienceMap2 as Map mode.

you mean using generalized categories instead of osm tags? this is already
possible by changing the render-theme.

Also, what are your thoughts about using proto-buf based protocol for
browser based rendering ?

I don't see any problems with it. it would make sense to not create tiles
twice. Though for javascript I would probably use a pbf code-generator. As
we had tiles stored in PostGIS already and I'm not used to javascript it
was easier to write a TileStache json provider that can be used for
kothic-js http://city.informatik.uni-bremen.de/~jeff/kothic/debug/. If you
want to test oscim-pbf in a browser the implementation in kothic-js should
be straight forward. when adding webgl renderer and proper themeing it
might actually become quite nice :)

Thanks for the great app!

Thank you! code-wise it is still rough on many edges as I'm working on too
many things concurrently. don't hesitate to report issues when testing it
with your tile-server.
